Power (physics) - Wikipedia
WebApr 5, 2024 · Power is work divided by time; hence the SI unit of power is joules/second. Scientists have given a name for this unit, and the unit of power in the SI unit is Watt (named after James Watt, the Scottish inventor of steam engines that helped launch the Industrial revolution.). 1 Watt = 1 Joule /second = 1 kg m2 s-3. Webpower (P) is measured in watts (W) work done (E) is measured in joules (J) time (t) is measured in seconds (s) One watt is equal to one joule per second (J/s). This means … One joule represents (approximately): The amount of electricity required to run a 1 W device for 1 s.The energy required to accelerate a 1 kg mass at 1 m/s through a distance of 1 m.The kinetic energy of a 2 kg mass travelling at 1 m/s, or a 1 kg mass travelling at 1.41 m/s.The energy required to lift a medium-sized … See more The joule is the unit of energy in the International System of Units (SI). It is equal to the amount of work done when a force of 1 newton displaces a mass through a distance of 1 metre in the direction of the force applied. It is … See more Zeptojoule 160 zeptojoule is about one electronvolt. The minimal energy needed to change a bit at around room temperature – approximately 2.75 zJ – is given by the Landauer limit. Nanojoule 160 nanojoule is about the kinetic energy of a flying mosquito. … See more In mechanics, the concept of force (in some direction) has a close analogue in the concept of torque (about some angle): A result of this similarity is that the SI unit for torque is the See more In terms of SI base units and in terms of SI derived units with special names, the joule is defined as One joule can also … See more The cgs system had been declared official in 1881, at the first International Electrical Congress.
